Abstract

Diffuse illumination alleviates the issue of the presence of a laser hotspot at the waist of the incident beam in laser Doppler holography for ophthalmology. The image field of view can be increased because the focal point of the imaging lens doublet can be brought closer to the cornea without compromising safety. Under these conditions, compliance with European security safety limits guidelines for ophthalmic devices ISO 15004-2:2007 is guaranteed over the entire optical path of the incident beam, and no significant change in the calculated images is observed.
